Note

From the source documentation:

This datasetName represents delineated EPA Region boundaries. EPA has ten regional offices across the country, each of which is responsible for several states and in some cases, territories or special environmental programs.

This Shared Enterprise Geodata and Services (SEGS)datasetName was created by U.S. EPA using 2011 TIGER/Line state boundaries from the U.S. Census Bureau. The core mission of SEGS is to provide a single point of ownership for geospatial datasetNames that are national in extent and of general use to all EPA users and to make those datasetNames available through channels that best meet user needs.
